I want to change my Terminal shortcut from Ctrl-Alt-t to Super-t (Super meaning the Windows key). So I go to Cinnamon Settings -> Keyboard and I attempt to change the existing keyboard binding.

I can successfully change the keyboard binding from Ctrl-Alt-t to Super-t, but Super-t doesn't work after the change. Terminal is still mapped to Ctrl-Alt-t. Is this the correct way to modify keyboard shortcuts in Cinnamon?

I having exactly the same problem. Looks like the default Ctrl+Alt+T shortcut can't be changed at all. What's even worse, I can't even define another shortcut to simply run gnome-terminal command, instead of x-terminal-emulator. I mean, one can add that shortcut, but it doesn't work at all

EDIT: The trick is to restore Keyboard setting under System Tools -> System Settings. When that's done, open the Keyboard settings and go to Shortcuts tab. Under Launchers there is Launch terminal which has Ctrl+Alt+T assigned by default. Now if you change the shortcut there, it will work!
